CBitmap

Please tell me I'm too dumb to find it in the MSDN. Maybe a cold and programming don't mix. I just don't get it...


Using VC6 SP5 MFC, I have a CBitmap object constructed from a file. I need a copy of said object to modify it without touching the original. So how hard can it be to create a copy of an object ?

Copy constructor ? Nope.
Assignment operator ? Nope.
Initialization method taking anything I could cast a CBitmap into ? Nope.

WTF ?

that's mfc for you, that and no DIB class wrapper.

Here's a <i>suggestion</i> (sorry API):

use 'LoadImage' to return an HBITMAP (ensure LR_SHARED flag is set in last param of LoadImage).

Use 'CopyImage' to get a copy of the image.

Use 'DeleteObject' on original HBITMAP.

Use 'FromHandle ' member fn of CBitmap to return CBitmap obj.

The returned CBitmap object should contain a copy of the file bitmap.

Does that help?

I'll give it a try, sounds better than anything I could find ;)

Thanks.
